What did the Haitian revolution involve?
What was thriving in the French colony of Saint Domingue by the 1700s?

Slaves and Haiti as a Colony.

Now by 'thriving' im going to assume you mean in trade. Post 7-Years War Sugar(Both raw and refined), Indigo and Cotton. Prior to the 7-Years war, Sugar and Coffee.

Explanation:

The Haitian Revolution of 1791 was a one of the most successful slave revolts in history. Haiti at the time was a French Colony and after the Revolution.By the lead of Toussaint L’Ouverture, The Haitian slaves had completely over-ran the French, to the point they pushed them out fully.

In Saint Domingue (Modern day Haiti), Two Times of thriving trade happened. Post and Prior 7-years war Trade. The Colonies main export was Sugar in both times. With Coffee, Indigo and Cotton also being main exports of Haiti.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.

i think the answer is : the declaration of rights and grievances
